Naturalisation in Extra-Tropical Countries. Ill 



speciosum, Gracilaria lichenoides (J. Agardh) and Gelidium glandu- 

 lifolium (Harvey) are marine jelly- weeds, well deserving of wide 

 trans location. 



Chrysanthemum cinerarifolium, Boccone. (Pyrethrum cinerarifolium, 

 Trevisan) . 



Austria. Furnishes the Dalmatian insecticidal powder. It is 

 superior even to the Persian powder as an insecticide ; it will keep 

 for years. It is prepared from half -opened flowers, gathered during 

 dry weather and exsiccated under cover. Best applied in puffs 

 from a tube. To be used also against aphides [W. Saunders See 

 further U.S. Agricultural Report for 1881-2.] Serves to keep fresh 

 meat for days from decay. 



Chrysanthemum Parthenium, Persoon. (Pyrethrum Parthenium, 



Smith.) 



Middle and Southern Europe. " Feverfew." The root, foliage 

 and flowers of this perennial herb are in request for medicinal 

 purposes since ancient times ; the variety with yellow foliage serves 

 for edging of garden-plots, ribbon- and carpet-culture. 



Chrysanthemum roseum, Adam. (Pyrethrum roseum, Bieberstein). 



Sub-alpine South -Western Asia. This perennial herb, with C. 

 coronopifolium (Willdenow) yields the Persian Insect-powder. 

 Effective against aphides. Centipeda (Myriogyne) could doubtless 

 also be converted into a strong insecticidal powder. 



Chrysopsis graminifolia, Nuttall. 



Southern States of North-America. This herb furnishes a fibre 

 of soft texture and silk-like lustre [K. Mohr]. 



Chusquea Guleou, E. Desvaux. 



Chili, Valdivia, Argentina. This bamboo does not often exceed 

 20 feet in height ; the autochthones on the La Plata-River use it 

 for lances. C. heterophylla and C. Cumingii (Nees) serve in the 

 same region for thatch-roofing [Hieronymus] . C. andina (Philippi) 

 grows in Chili near the snow-line. 



Cicer arietinum, Dodoens.* 



South-Europe and South-Western Asia. The Gram or Chick- 

 Pea, introduced into China during the 14th century [Bretschneider] . 

 An annual herb, valuable as a pulse f or stable-food, but an extensive 

 article also of human diet in India. Colonel Sykes counted as many 

 as 170 seeds on one plant. In Spain, next to wheat, the most 

 extensively used plant for human food [Honorable Caleb Gushing]. 

 The plant suppresses weeds, and is of special service in the rotation 

 of crops. The return is in about four months. The seeds can be 

 converted into pea-meal, or can be used in various other ways for 

 culinary purposes.
